It consists of an instrument, a personal computer, and disposable fluidic cartridges. The analytical sensitivity and specificity of the GeneXpert enterovirus assay (GXEA) were determined with a panel of 63 different enterovirus serotypes and 24 other microorganisms, respectively. The potential for blood, hemoglobin, white blood cells, and excess protein to interfere with the assay was also assessed. The performance parameters of the GXEA were determined at three sites with 102 cerebrospinal fluid (CSF) samples obtained from patients with suspected meningitis. All samples were tested for enterovirus RNA with locally developed reverse transcription-PCR (RT-PCR) assays at the trial sites and with a seminested RT-PCR and an analyte-specific reagent (Cepheid) at a reference laboratory. The 5\u2032 nontranslated region was the target for all of the PCR assays except the seminested RT-PCR, which amplified a VP1 sequence. The VP1 amplicon was sequenced to identify the enterovirus types. Consensus reference laboratory RT-PCR results were used to classify cases of enteroviral meningitis. The GXEA detected all of the enterovirus serotypes and none of the other microorganisms tested except rhinovirus 16. The assay was unaffected by moderate amounts of blood or blood components. Thirty-six (35%) of the CSF samples tested had at least one positive PCR result. Eleven different enterovirus serotypes were identified in the positive samples. The GXEA had a sensitivity of 97.1% (95% confidence interval [CI], 84.7 to 99.9%) and a specificity of 100% (95% CI, 94.6 to 100%) for the diagnosis of enteroviral meningitis.<\/jats:p>","DOI":"10.1128\/jcm.01718-06","type":"journal-article","created":{"date-parts":[[2007,1,25]],"date-time":"2007-01-25T05:51:58Z","timestamp":1169704318000},"page":"1081-1086","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":87,"title":["Multicenter Beta Trial of the GeneXpert Enterovirus Assay"],"prefix":"10.1128","volume":"45","author":[{"given":"Christine B.","family":"Kost","sequence":"first","affiliation":[{"name":"Emory University School of Medicine, Atlanta, Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beverly","family":"Rogers","sequence":"additional","affiliation":[{"name":"Children's Medical Center and the University of Texas Southwestern Medical Center, Dallas, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
